I do have mixed opinions about Valvano. I also wonder exactly what really goes on at all places, etc.
The "30 for 30" was really good. Living in the area, not only do I remember watching it all as a young kid, but I've heard so much about it for so many years. Even so, it was still so very interesting to watch.
A couple notes. The ACC had both a 3-pt line and a 30-second shot clock that year. Funny thing about the shot clock...it turned off with 4 minutes to play. That's why you saw a team hold it for 3 1/2 minutes.
It was so experimental. The 3-pt line was ridiculously short (17' 9" I believe) and the shot clock was turned off when it mattered most.
Even today though....you can't tell me 35-seconds isn't ridiculously long. Some games it never comes into play until late in games when a team just holds it and forces several late game fouls.
I think it was slightly better then, b/c you had a chance to play tough D and get the ball. Back then you had to dribble. Today (and for the last 20+ years) a PF can easily keep possession of the ball b/c your allowed to carry it, etc.
Just put it at 24-seconds and reward defense and possessions rather than start fouling with several minutes to play...
